Harvard has long ceased being an excellent educational institution. Any number of state Land Grant Schools are better and more rigorous.
Harvard is merely about access and connections at this point.
Also true about that college in New Haven.
But, be fair - over a lifetime those intangibles are worth close to a billion dollars, and it's the only path to ruling by decree over larger and larger swaths of the nation, starting at age 22 (or 25 if you go to law school).
If money, power, and the sex that accompanies both are something you want, you can't go wrong at Harvard OR the other one.
